I have to relogin to my Qt account too often

I come back to the qt forums every several days/weeks, I suppose. And everytime it's asking me to confirm that I want to login to the forums with my Qt account. At least it doesn't ask me for my user name and password, IIRC. And today it even asked me for my user name and password (after not having logged in for maybe 2 weeks). Please make it remember me for a (much) longer time, preferably forever
Note that the issue is not in my system as I'm logged into other sites too and none of them log me out all the time like that.
